i’m markus, i design clean, intuitive, human products and use ai to compile and power every experience. i’m ready to collaborate with founders, teams, and anyone building something new.
here’s what i’ve been building over the years:
27yrs-now:
- built shamir-secret-manager, a 500-line python cli for splitting and recovering seed phrases with shamir secret sharing
- crafting obliso, a rust + swift macos/ios app for easy and secure n-of-k seed management
- prototyping mondecai, a local-first ai that plays conversations via monte-carlo search, private beta
- game creator + community scout at rosebud.ai, shipping touch-first games with generative pipelines
26yrs:
- shipped a minimal bitcoin wallet demo with live data using srcl terminal ui components
- designed and launched a jobs web-app for scherer ingenieure helping high-skill engineers find roles
- spun up tooling and visual frameworks for micro ai products
- explored brand systems for studios and solo builders
25yrs:
- product lead at scherer ingenieure, rebuilt the front-end for clarity, structure, and a unified visual language
- integrated deepseek in a website’s local-storage search using onnx
- experimented with LoRA training in flux and custom stable-diffusion safetensors
- built workflow dashboards and ux improvements that boosted team efficiency and pivoted toward resilient, behind-the-scenes systems over showcase pieces
24yrs:
- designed the app and landing page for photure, a p2p media platform minting uncensored nfts; team hit 30k downloads and raised $765k at a $5m cap
- freelance at the studio dao, collaborating with a yc + techstars mentor on site and brand
- wove ai-assisted flows deeper into my design stack
23yrs:
- 0→1 product design at plasmo; platform now voted best chrome extension (producthunt 2024 + 2025) with 11.6k stars on github
- built pylearn, a beginner-friendly coding app prototype
- collaborated with constitution dao, a one-off dao that crowdfunded $47m to bid on a u.s. constitution copy
- freelance branding + ui/ux for hdghog, a decentralised exchange led by an early facebook novi founder
21–22yrs:
- designed, built, and oversaw fabrication of a smart mushroom cultivation unit for my bachelor’s thesis
- produced cad visuals for an exhibition build for sonnleitner, later realised at bau19 munich
19–21yrs:
- switched to industrial design to fuse spatial thinking with rapid prototyping
- built and maintained id-regensburg.de, a showcase of standout student work
- deepened systems thinking across ui/ux and digital-physical intersections
17–18yrs:
- declined an architecture place at tum after realising code iterates faster
- became on of the earliest testflight testers for christian selig’s apollo, sending feedback that shipped in the reddit client used by millions
- one year computer science: grasped coding basics, git, and algorithms
- interned at communiaсs, creating svg animations, wireframes, and visual concepts for e-commerce sites like eterna, bavaria-yachts, and knaus that went live
14–16yrs:
- jailbreak enthusiast: dissected ios, installed cydia tweaks, debugged crashes, rolled back firmware
- ran private minecraft and wow realms, managing plugins and small friend communities
- shipped dozens of micro-sites and experiments (html, css, first js); all offline now, each sharpened my front-end instincts
the faster everything accelerates, the more i care about clarity, friction, and form. i’m leaning in, blending design, code, and ai to build things no single role could fully define.
